… own or inherited method (colbymchenry#2479) A C++ call written with no receiver, or through `this->`, inside a method was matched by its name alone, so another class's method of that name won by file proximity: protobuf's generated `Api::operator=` calling `InternalSwap(&from)` reached `Any::InternalSwap`, `Any::InternalSwap`'s inherited `GetArena()` reached `Arena::InternalHelper::GetArena`, and googletest's `~linked_ptr() { depart(); }` reached `linked_ptr_internal::depart`. matchMethodCall now resolves C++'s implicit `this` the way it resolves a typed receiver: the calling method's class, then the classes it derives from (its own base edges, through colbymchenry#2440's cppMethodOf), then the classes it is nested in, with the overload the arguments fit. The call's shape is read at its column (the extractor drops `this->` and some receivers it can't spell). A free function, a parameter or local of the name, a dependent base reached by a bare call, a namesake class in another translation unit and a member a macro may declare all leave the call to the name strategies.

…ymchenry#2480) A data-router `lazy` loader resolves to the route's properties, and many pick their page from the module they load: luci-go milo/ui's `lazy: async () => { const { TestTab } = await import('…/tabs'); return { Component: TestTab }; }`, `const { default: Component } = await import('./pages/Login')`, `import('./x').then((m) => ({ Component: m.Page }))`, `({ Component: (await import('./x')).Page })`, React Router 7's `lazy: { Component: async () => (await import('./x')).Page }`. scanRoutes recorded only the first `import('…')` as `lazy-import:<spec>`, and resolution linked the module's default export, else its `Component`: a different page, or nothing (milo/ui's tabs barrel has neither). lazyRouteReference reads the loader: its `Component`, or the page its `element` shows, followed through the loader's bindings (destructured `await import`, a module binding, `.then` callbacks, `Promise.all`, the v7.5 object form), and the one lazily imported export a guard shows (`<AgeGate><FireworksPage /></AgeGate>`). A loader that returns the module keeps `lazy-import:<spec>`; one this does not read (a helper's, `.then(convert)`) keeps its first import, as before; one that hands over only a `loader` renders nothing. `async lazy() { … }` methods, which scanRoutes skipped as entries, are read too, and comments no longer hide an import's specifier. The picked export is named the way Vue Router and Angular name a lazy component, `import:<path>#<export>`, so sync's module-tail retry (colbymchenry#2422) parks and retries it unchanged, and it resolves through colbymchenry#2436's exportedComponent, barrels included. React is registered before Vue Router and Angular, so it answers only its own routes' references (tsx or jsx, which theirs never are). lazyModules (colbymchenry#2452) names the files a picked export is read from, so a sync that moves it redraws the route.

…ed default (colbymchenry#2481) colbymchenry#2432 made a default import read the module's own `export default` statement, and its merge pointed colbymchenry#2433's `require('./x').default` fallback (esmDefaultExport) at the same reading. Nothing in the suite pinned that path with a guessable helper above the default: colbymchenry#2433's fixture keeps its helper unexported. Two cases: - React Native's AnimatedColor shape, an exported helper above `export default class AnimatedColor`, loaded with `require("./AnimatedColor").default` and `const { default: Color } = require("./AnimatedColor")`. With the first-exported guess both `new` calls instantiate the helper. - `export default abstract class Repository` below an exported `connect()`, extended by `class Users extends Repository`. With the guess the `extends` edge is missing. Both fail with e47cb25's resolver (before colbymchenry#2432). On main, putting the guess back on the require path fails only the first, and dropping `abstract` from the declaration pattern fails only the second. The CHANGELOG's default-import bullet now says `require('./x').default` is read the same way. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Review comments at @CHANGELOG.md:
- Line 455: Revise the C++ changelog entry’s claim about calls resolving to
members of a class containing the current class. Clarify that enclosing-class
name lookup does not imply an unqualified call to a non-static member is valid;
limit the call-resolution claim to static members or calls through an explicit
enclosing object, or describe this case as name lookup rather than a call C++
would make.

Merges upstream
mainthrough1ce1167e(upstream colbymchenry#2479, colbymchenry#2480, colbymchenry#2481) intofork/consolidated.colbymchenry#2479 (C++): a call with no receiver, or on
this, inside a member function (or a lambda in one) links to the member C++ name lookup finds: the class's own, else an inherited one, else an enclosing class's, with the overload the arguments fit. Upstream implements it insrc/resolution/name-matcher.ts, which the fork deleted, so the merge keeps that deletion and ports the rule to the native resolver:codegraph-kernel/src/resolve/cpp_implicit_this.rs, hooked inpipeline.rsright aftercpp_plain_call. It reads the call's spelling at its column, finds the owner class (in-class or out-of-line definition), walks the enclosing classes (keeping the declaration that holds the code, else the file's, else the included ones), skips a base that depends on a template parameter for a bare call, stops at a class whose macro may declare the name, and drops a call that names a parameter or local.cpp_receivers.rs: an array declarator now binds a local, and a subscript of a one-dimensional class array (Item items[2]; items[0].Clear()) takes the class as the element type. Upstream's test needs this; the fork previously refused the call.torture-multilangkeeps its target; only itsresolvedBychanges fromexact-matchtoinstance-method(a bare C++ call in a member).colbymchenry#2480 (React Router): a lazy route links the page its loader picks.
src/resolution/frameworks/react.tsmerged as is. The kernel's React claim table (tables.rs) now also claimsimport:<path>#<Export>references, as the TypeScriptclaimsReferencedoes; without it the new references were never handed to the framework resolver.colbymchenry#2481: tests only; they pass unchanged.
Conflicts:
docs/design/framework-coverage.md(kept the fork's React Router row and appended upstream's lazy-loader sentence);name-matcher.tsstays deleted. CHANGELOG: the merge had re-inserted 11 entries the fork already carries; cut back to upstream's three changes (C++ entry, React Router lazy entry, the updated default-import entry). README merge point moved to1ce1167e.Checks: full suite 683 files / 8734 passed, 39 skipped (the only failure was the golden dump above, re-baselined); the three new upstream test files pass 39/39; no worker crashes; kernel builds clean under clippy
-D warnings;eval:precisionheld on gin (3/3), vite (8/8) and jq (0/0, no cases). Not measured: edge-level before/after on a real C++ corpus, because none is in~/cg-scratch/eval-repos(rocksdb/protobuf were the motivating repos).README rows checked: merge point (2 places) updated; no fork-vs-upstream row changes.
Lands as a merge commit (not squash) to keep upstream ancestry.
